Ferns
Ferns bring a broad range of frond shapes, from crisp rosettes and creeping growth to upright crowns and long arches. Fine, feathery, rippled and strap-like textures appear in terrarium plants, hanging ferns and larger floor specimens.

About Our Filters
Filters help you narrow things down fast and without guessing. We put a lot of time and effort into keeping filter values consistent across the shop by cross-checking references and validating them against real-world indoor growing and handling.
Use them as guidance, not guarantees. Homes vary a lot, so for the full context (and any exceptions), open the product page and read the description.
How filtering works
- Filters stack: each selection narrows results.
- Multiple picks in one filter are usually either/or within that filter.
- Undo anytime: click a selected option again (or clear filters).
Safety
- Non-toxic: not known for relevant chemical toxicity for common pets (chewing can still cause irritation).
- Non-toxic & Pet Friendly: stricter shortlist that also avoids many physical hazards like spines, sharp tips, thorns, and bristles.
Common care filters
- Light level: Low indirect → Full sun/direct.
- Water Needs: Low / Medium / High.
- Humidity Level: Normal (40–50%) / Moist (50–60%) / Humid (60–80%+).
Growth & size
- Growth Habit: climbing, trailing, crawling, upright, self-heading, clumping, rosette.
- Needs support? none / optional / needed.
- Delivered size: pot size + plant height at shipping.
- Max size indoors: realistic long-term height + spread indoors.
Looks & botanical browsing
- Leaf Shape & Size + Foliage Colour: quick visual categories.
- Plant Type / Genus / Family: browse by broad group or taxonomy.

Ferns
Ferns are a broad spore-producing plant group not one single family. Indoor fern selections often mix several families and several distinct growth forms.
Indoor fern growth forms
Indoor ferns include nest-forming rosettes, finely divided fronds, creeping rhizomes and stoloniferous species. Mature width, frond length and growth structure describe the outline of each plant. Asplenium builds a central nest, Nephrolepis produces arching fronds from rhizomes and runners, and compact specialist ferns stay close to the pot.
Crowns, rhizomes and mature spread
Fresh croziers or fronds show active growth. Fine-leaved ferns create soft texture and a wide spread. Strap-leaved nest ferns produce a stronger architectural shape. Creeping rhizomes and stolons can extend across the container and form new growth points.
Container width matters for plants that spread from the base. Open space around a nest-forming crown allows new fronds to unfurl cleanly, while rhizomatous and stoloniferous ferns need room for basal spread.
Leaf texture and moisture rhythm
Thin fronds respond quickly to changes in root moisture and dry air. Broader nest ferns carry more substantial leaves and a slower visual rhythm. Steady root moisture supports healthy fern growth, with the exact rhythm following the species and substrate.
Leaf-tip colour can reflect dry roots, mineral build-up, low humidity or abrupt environmental changes. The pattern and position of damage help narrow the likely cause.

Frequently Asked Questions About Ferns
Are ferns hard to keep indoors?
Some are fussier than standard leafy houseplants, but ferns are not automatically difficult. Boston fern usually wants steadier moisture and higher humidity than rabbit’s-foot fern, so success depends more on the type of fern than on the word “fern” alone.
Do indoor ferns like low light?
Most indoor ferns prefer bright indirect light or light shade rather than deep low light. They usually dislike direct sun, but a very dim spot can leave them thin, sparse and weak-looking.
How should indoor ferns be watered?
Not all ferns are watered the same way. Many common house ferns do best when roughly the top 10–20% of the potting mix has dried, while Boston-fern types usually want steadier moisture and rabbit’s-foot or other epiphytic ferns can often dry a bit further before watering again. What they generally do not like is staying sodden for long periods.
Why do fern tips turn brown?
Brown tips usually mean the plant has been too dry, the air has been too dry, or the water quality is poor for that type. Direct sun, cold drafts and roots staying wet for too long can also damage fern growth, so brown tips need context rather than one stock answer.
Are ferns safe around pets?
Many true ferns, including Boston fern and rabbit’s-foot fern, are considered non-toxic to cats and dogs. The catch is that some plants sold under fern names, such as aspaagus fern, are not true ferns and can be toxic.

Die Pflanzen waren prima verpackt und ein heatpack war im Paket enthalten. Die Lieferzeit hat 2 bis 3 Tagen gedauert, was aus meiner Sicht wirklich gut ist. Alle drei Pflanzen haben die Lieferung gut überstanden. Ich habe mich auf Hoyas spezialisiert und habe schon die nächsten Pflanzen meiner Wunschliste auf der Website gefunden. Daher wird die nächste Bestellung nicht lange auf sich warten lassen.

The plants are carefully packaged and arrive in great conditions (I’m based in Spain) and they’re always there to help in any way they can with your purchase.I have and will always recommend Foliage Factory to every friend I can. I’m not only satisfied with their plants and prices, but their customer service is exceptional.

Very healthy and well packed plant. Unfortunately there was one plant that ordered couldn’t be delivered as it was out of stock hence 1 star less.

Die Sendung kam leider in keinem guten Zustand bei mir an, kann passieren. Habe mich darauf hin sofort an Foliage Factory gewandt und habe selten einen so guten, schnellen, freundlichen und kulanten Kundendienst erlebt.

Everything arrived in good condition and very well packed - it wasn't easy with a fragile plant and a heavy bag of substrate. I recommend it!

Bester online-Pflanzenhandel den ich kenne (habe davor 4 andere ausprobiert). Eine teure Pflanze wurde beim Transport beschädigt und mir ersetzt. Der Kontakt dabei war auch sehr nett (danke Jan) und hat mir gut geholfen. Die anderen Pflanzen sind in einem sehr guten Zustand, keine Schädlinge, super Bewurzelung. Nur zu empfehlen! :)

The plants have arrived in perfect condition, the roots and the foliage so so healthy! I had problem with 1 plant out of 16 and they have responded to my email almost instantly and the issue was resolved straight away. I'm really impressed and satisfied, definitely getting more plants from them again!

I received perfectly heathy and absolutely beautiful plants, even bigger than expected. The delivery within Europe was really fast. I think Foliage Factory has one of the best plant web shops in the internet. It‘s just great to get so much informations about the plants. I will definitely order again :)
